Žemės ūkio ir pramonės atliekų poveikis vasarinių kviečių augimo dinamikai ir chlorofilo a ir b sintezei

Abstract

The experiment was carried out in the Pomological Garden of Aleksandras Stulginskis University in 2015. Medium heavy loam and sandy loam soil are the types of experimental soil. The analysis of soil characteristics showed that pH of the medium heavy loamy soil was 6,9, organic carbon content was 2,17%, 0,171% of total nitrogen, available phosphorus (P2O5) 146 mg kg-1, potassium (K2O) 183 mg kg -1; pH of the sandy loam was 5,7, organic carbon content of 1,41%, 0,121% total nitrogen, available phosphorus (P2O5) 62 mg kg-1, potassium (K2O) 84 mg kg-1. It was determined that the plants, which were growing the most intensively, were found in the soil fertilized with the largest 30 t ha-1aplication rate of agriculture and industry waste. The essential highest chlorophyll a (1, 50 mg kg-1) content was determined at the medium heavy loam loam soil fertilized with the highest rate of used product during the experiment. Essential chlorophyll b content changes in growing spring wheat on medium loam were noticed when 18, 24 and 30 t ha-1 rate of agricultural and industrial waste has been interrupted in the soil. It was determined that the chlorophyll b content had no significant influence on the plants leaves when the spring wheats were grown in the sandy loam soil which was interrupted by different rates of agricultural and industrial waste.
